Canadiangirl,
We just went on our first WDW family trip this past Aug. We also stayed at POR. I really liked it for our first stay. The pool is great. I know you are prolly trying to figure out how to see and do all that you can while you are there. I know we tried it too. It was not realized however. Still lots for us to return for.
I say take an afternoon out and relax by the pool at POR. It is a very nice pool area.
We took 3 DD's (13, 8 &6yo). They LOVED shopping at the
disney store in DTD. We got them each thier own disney gift card. I even asked thier grandparents to contribute to each gilrl's funds. That way hubby and I could relax about finances while we were there. I told them they had thier gift cards money and when it ran out...well.... it ran out. End of money discussion. It was such a wonderful way to show them that money only stretches so far then it is gone. My middle DD got a hoot out of keeping track how much was remaining on her card after each purchace. It was funny.
Our best friends also went with us (they took thier 2 DS's- 16 & 12 yo) They really got a kick out of Pizza Planet games @ Hollywood Studios. Not sure of the draw but thay liked it anyhow. I found it sort of expensive (but I can not remmeber exact prices though-just that it was more than it was at home). I suggest giving them a limit as soon as you board the plane--unless money is not an issue for you all. It was for us.
Oh! And don't miss the 3-D shows. They were more impressive than I thought they were going to be-my picky techie hubby was even impressed. If your boys are big Star Wars fans then do not miss the Star Wars ride. I even enjoyed that one. I didn't even suffer my usual motion sickness either. I was shocked about that blessing.
From what my hubby and his BFF told me and my BFF (hubby's BFF's wife

) I think your boys may really enjoy EPCOT. My BFF and I didn't see much of EPCOT though as we had plans at the GF Spa that day for an Aromatherapy Massage--80 mins of heaven.
Don't miss Soarin either.
My faves so far (and this is not particular order):
Rockin Rollercoaster
Tower of Terror
Soarin
Haunted Mansion
Have a great trip to the World!!!
